How on earth would an autopsy show whether Terri could, with rehabilitation, experience improvement in her condition??? Autopsies show what is, not what might be.

1) Terri received many years of physical therapy, occupational therapy, and rehabilitive care without any improvment in her condition. Why do you think she was on a 'feeding tube' to begin with. She has no ability to swallow independently.
2) An autopsy would demonstrate what areas of the brain were damaged and to what extent. It would even show whether or not CSF and scar tissue had replaced the areas of her brain allowing her to feel pain, talk, and have cognitive abilities. The autoposy would provide data that a MRI, CT scan, or xray could not.
Terri's husband spent $100,000 have thalamic stimulators implanted in her brain in an experimental effort restore her brain activities in the early 1990's. Does that sound like a man who was disinterested in his wife's rehabilitation?
